In the frame assembly A, the side frame 4 and the side plate 11 of thebackplane 1 are fixedly connected, and the fixing plate 21 of the frontframe 2 is fixed on the side frame 4, to ensure stability of theconnection among the front frame 2, the side frame 4, and the backplane1. In the meantime, the side frame 4 and the side plate 11 of thebackplane 1 coordinate to form a step surface 114 for supporting thefixing plate 21, and one side, facing the base plate 12 of the backplane1, of the fixing plate 21 is supported on the step surface 114, to makesure that the fixing plate 21 is accommodated in the step surface 114 ina direction parallel to a light emergent surface of the display panel 6.A support limitation structure for the display panel 6 can be formedbetween the pressing plate 22 of the front frame 2 and the step surface33 of the elastic pad 3 to ensure stability of the display panel 6 afterinstallation. After the front frame 2, the side frame 4, the backplane1, and the elastic pad 3 are installed, an outer surface of the fixingplate 21 of the front frame 2 is not higher than an outer surface of theside plate 11 of the backplane 1, and a projection of the side frame 4and a projection of the elastic pad 3 in a plane of a side surface,facing the pressing plate 22, of the side plate 11 of the backplane 1 islocated within the side surface, facing the pressing plate 22, of theside plate 11.
